MACHINE FOR CROSSGROOVING AXLE-TREES.

SPECIFICATION forming part of Letters Patent No. 319,361, dated .Tune 2,1885i.

Application filed March 3, 1885. (No model.)

To @ZZ whom it may concern.-

Be it known that I, GEORGE WATSON, a citizen of the United States,residing at St. Charles, in the county of Winona and State of Minnesota,have invented a new and useful Improvement in Machines forCross-Grooving Axle-Trees, Bolsters, 815e. of which the following is adescription.

` Figurel is a plan View of the machine. Fig. 2 is a side elevation ofthe same in section through the line x m of Fig. l. Fig. 3 is a verticalsection through the lineyy of Fig. 1. Fig. 4 is a detail of one oftheslotted arms for adjusting the frames of the side spindles; and Fig. 5is a view of an axle, showing the character of the grooves or gains thatmy machine is designed to cut.

The object of my invention is to provide a machine for crosslgroovingvehicle axletrees, bolsters, sleigh-raves, Ste.

The axle-trees and bolsters of wagons have usually three cross groovesor gains in them, the middle one of which is adapted to receive thelongitudinal reach-bar, and the side ones adapted to receive the houndsof the wagon in fitting together the running-gear.

My invention consists in a machine for simultaneously cutting thesethree cross-grooves and giving to the side grooves either a straighttransverse cut or an oblique cut, according to vthe lay of the hounds,as will be hereinafter fully described.

In the drawings, A represents the stationary table, which is supportedat its four corners upon legs B, mounted upon basebars O. To the lowerends of these legs are fastened horizontal longitudinal bars D, one oneach side of the machine and supporting the crossbar E. The horizontalbars D are connected to the legs by slots a and set-screws b, so as topermit a vertical adj ustment of said bars, and the cross-bar carried bythem has about its middle a bearing, in which is stepped a verticalspindle, F, Fig. 3, provided with a bandpulley, F', and journaled in abearing above and passing through the stationary table, and having arevolving cutter made in the form of a hollow auger.

To the bottom of the table A are fastened transversely-arranged bars G,in which and on the transverse bar E is arranged on each side atransversely-sliding side frame, G, whlch sliding frames are connectedto the bars E and G by flanged andgrooved guides, Fig. 2, In each ofthese sliding ,side frames is carried a vertical spindle, G2, having aband-pulley, G3, which spindles protrude through slots d in the tableand carry on each side of the central spindle a revolving cutter orhollow auger.

On the top of the table is arrangedA a longitudinally-slidingrectangular frame, H H', of which the side bars, H', are matched to fitthe sides of the table A, to form guides, and lie 1n the same plane asthe table, and of which the end bars, H, are arranged transversely abovethe level of the table and serve to advance the axle-tree or other workto be acted upon by the cutters.

To the bottom part of this rectangular frame are adj ustably fastened bya slotand set-screw, e, the'slotted arms I, one on each side of themachine, which bars pass at right angles under the top section of thetwo side frames, G', and from which top section of each side frame apin, f, depends into and passes through the slot ofthe arm. These armsare capable of being set straight with the table or slightly oblique tothe same by these set-screws e, and may also be moved closer to orfarther from the center by reason of their slots e, for the `purposehereinafter described.

The operation of this machine is as follows: If an axle-tree is to beoperated upon,the two side spindles are set a distance from the centerspindle equal to the distance between the grooves or gains to be cut,and if these side gains are straight or right-angular the side arms, I,are adjusted parallel to the side bars, II, of the sliding frame, asshown in dotted line in Fig. l. The spindles bearing the cutters newbeing setin motion by their respective belts, the aXle-tree is laid onthe table up against one of the bars H of the sliding frame, as indotted lines, Fig. 1, and the latter is vslowly advanced over thecutters, which cut the transverse grooves or gains in the axletree. Ifthe two side grooves or gains are to be cut obliquely, as is frequentlyrequired for the accommodation of the hounds, as in Fig. 5, the arms lare set obliquely to the side bars,

IOO

H', of the table-frame, and txed at the proper angle by the set-screwsc. Then as the frame H H is advanced with the axle tree these obliquearms I eXerta cam action on the pendent pins f of the side frames, G',carrying the side cutters, and a slight transverse motion is given theside cutters in the slots d d, sufficient to produce an oblique cut, theinclination of which may be varied by the adjustment of the arms I.

The machine can also be used as a tenoningmachine, and also as a shaper,by sim ply screwing different heads onto the tops of the spindles.

Having thus described my invention, what I claim as new isl. A machinefor cutting cross grooves or gains, consisting of the combination of atable, a vertical central rotating spindle bearing a pulley below and acutter at its upper end, and vertically-arranged frames disposed inguides upon opposite sides of the central spindle, and bearing each avertical spindle having a pulley below and a cutter at its upper end,the said frames being made adjustable to or from the central spindle,substantially as shown and described.

-2. A machine for cutting cross grooves or gains, consisting ofthecombination of a table,

a vertical central rotating spindle bearing a 3o pulley below and acutter at Vits upper end, vertically-arranged frames disposed in guidesupon opposite sides of the central spindle, and bearing each a verticalspindle having a pulley below and a cutter at its upper end, the saidframes being made adjustable to or from the central spindle, and asliding frame, H H', arranged to move in guides across the table,andhaving one of its set of bars Iiush with the table and the other pro-4o jecting above it, substantially as described.

3. `A machine for cutting cross grooves or gains, consisting of thecombination of a table having slots d, and a central vertical rotatingspindle bearing a cutter, sliding side frames 45 carrying vertical sidecutters, and having a motion at right angles to the feed motion of thetable,and a sliding feedframe,H H', having adjustable arms I engagingwith the side frames, and adapted to adjust the latter by the feed 5omovement ofthe frame H I-I',as and for thefpurpose described. f
